CUSHION SEAT.

Application filed April 9, 1927. Serial No. 182,400.

This invention relates to cushion seats especially adapted for use in automobiles and to be adjusted in accordance with theweight of the person who most frequent-lyoccupies the seat.

The object of the invention is to provide a resilient cushion seat which will automatically absorb the shock of the weight of a person on the seat and wherebyrthe resistance of the cushion will increase in proportion to the distance it is depressed.

Another object of'the invention is to provide a means for an initial adjustment of the cushion to compensate for the weight of a person who habitually occupies the seat in order that the cushion will not yield downwardly any greater distance when a heavy person is to occupy it than when a light person is to occupy it.

The above and other objects will be more fully disclosed in the following specification and will be exemplified in the accompanying drawings, in which a Figure 1 represents an underneath plan view of a cushion seat embodying the invention.

Figure 2 is a longitudinal section through the same taken on the line 22 of Figure 1, the cushion being shown top side up.

Figure 3 is an enlarged fragmental section taken on the line 3'3 of Figure 1, the cushion being shown top side up.

Figure 4; is an enlarged section taken on the line 14 of Figure 1, the cushion being shoWn top side up.

In carrying out the invention, a rectangular shaped frame 6 is provided composed of wood or other suitable material and com prises the side bars 7 and 8 and the end bars 9 and 10, and mounted above said frame and adapted to fit within the confines of the same is a second frame 11 preferably composed of angle irons having the vertically disposed sides and ends 12 and the horizontally disposed legs 13, having resting and secured to them a seat board 14.

The seat board 1 1 is suitably padded as at 15 and is covered with leather or a fabric 16, said fabric extending downwardly over the sides of the frame and being secured to its outer surface by any suitable means.

Secured by means of screws 17 in the corners of frame 6 are the metallic fittings 18 which are identical of construction. A fit-' ting 18 comprises the vertical sides 19 and the bottomplates 20 and extending upwardly, from said bottom plates is a hollow boss 21 provided at its top with an aperture. 22.

Extending downwardly from each corner of the legs 13 of frame 11 is a boss 23 pro vided at its center with an aperture 24 in vertical alignment with the aperture 22 and passing through these apertures is a bolt 25, the head 26 of which rests upon the upper surface of leg 13 of frame 11 and the lower, end of which extends into the hollow of the boss 21 and has threaded on to it the nuts 26. Surrounding each bolt 25 is a helical spring 27, the ends of which contact respectively I with the legs 13 and the plate 20, said spring being held from lateral displacement by means of the bosses 23 and 21. The spring 27 is less in diameter at its top than at its hot tom and is tapered to resemble the frustum of a cone.

Secured to the side and end bars of frame 6 by means of screws 28 are guiding members 29 each of which is preferably formed of strap metal and shaped so as to form the socket 30 for the reception of the ends of the flat bow springs 31, there being one of such springs for each side and end of the frames 6 and 11 and which are interposed therebetween, the ends of a-spring abutting against the inner face of the frame 6 and the central portion of the same abutting against the outer surface of legs 12 of frame 11. The portion of each guide member 29 opposite to its socket 30 forms a bumper to limit the lateral movement of seat frame 11 and thereby protects the bow springs 31 from excessive pressure. Said guiding members 29 form loop supports for the bow springs 31 in which said springs are freely movable, and yet by which they are kept in place without being weakened by having holes made therethrough to receive screws or like attaching means. 2

By this construction it will be obvious that thecushion top 15 may have both longitudinal and lateral movement with respect to frame 6 and said movement will be yielding and gentle in nature and the springs will. always return the cushion to normal position when occupied.

By the above recited construction it will be obvious that the seat will be cushioned against both side and lengthwise movement as well as upward and downward movement.

WVhen a person of light weight is to occupy the seat it may be left in the position with respect to frame 6 as shown. When a heavier person is to occupy the seat the nuts 26 may be adjusted to draw the seat downwardly With respect to the frame 6, thus limiting the upward and downward movement of the cushion as Well as increasing the resistance of the springs to compensate for the additional load due to the use of the tapered springs.

Having thus described my invention What I claim is:

1. In a device of the character described, a seat platform, a main frame beneath said platform, and an inner frame secured to the under side of said platform and adapted to move up and doWn Within said main frame, horizontally extending flat how springs, loop supports in which said how springs are freely movable to cushion said inner frame with regard to lateral movement Within said main frame, and bumpers carried by said 'main frame to guide the vertical movements of said inner frame therewithin, said bumpers performing also the function of loosely maintaining said how springs in the operative positions.

2. In a device of the character described, a seat platform, a main frame beneath said platform, an inner frame secured to the under side of said platform and adapted to move up and down Within said main frame, a plurality of coil springs positioned yieldingly to support said platform and permitting lateral movement th ercof, horizontally extending flat bow springs,'loop supports in Which said bow springs are freely movable to cushion said inner frame with regard to lateral movement Within said main frame, and bumpers carried by said main frame to guide the vertical movements of said inner frame thereWithin, said bumpers performing also the function of loosely maintaining said how springs in the operative positions.

In testimony whereof I hereunto affix my signature.
